said bracket a, affording accommodation for thepe'ripheral portion of the power pulley 79, as shown'in Figs. 2, and 4.

The power shaft is also supported in bearings a a, a on the table a. An eccentric p, on said power shaft P, operates the bolt 6', by means of the eccentric sleeve 6, (Fig. 2) and pitman rod 6 which latter is pivotally connected to the said bolt 6. The bolt-b, is slidably mounted in the standard 6 affixed to the table a, and locks the intermittently rotatable transfer member D,

while thepunches are doing their work as hereinafter-set f0rth,the outer endof said V 7 bolt protruding at the proper time into one of the recesses "d, (Fig. 8) formed for the purpose in the rear disk D, of said intermit- I drical blank holdersd, cl d as shown in Fig.4). 5

"Said gear 7k, is loose upon the shaft K, and is driven l intermittently-by the gear r,-affixed to the intermittently rotatable} shaft R, having aflixed' to it the intermittent gear 1",which engages with the intermittent gear affixed to the constantly rotating drive shaft K, These two intermittent gears W, and r, are shown in detail in Fig. 3, by reference 1 gear 70 tate three times to effect a complete rotation ease particularly to: rig- '24; a

to which it will be seen thatthe gear 74: has only one toothed peripheral segment k while the gear 7?, has three toothed-peripheral segments the' intervening spaces r being concave and conforming to the toothless peripheral pitch k, of the drive Thus the drive. gear 70 will roof the intermittent gear r.

A crank 10 ,011 the power shaft P, effects the reciprocation by means of the pitman p of the rod'C, which carries the'punches, at the forward end of the apparatus, said rod C, extending through the intermittent rotor "D, and having mounted'upon its forward end the four armedcross head C.

Therear portion 0,of the slide red C, is of angular form in cross section, preferably square, and is mounted in a bearingstandard c, rigidly secured to the table a, and having a bearing and cap adapted to the angular cross section of said rear portion 0, of the rod 0. This structure prevents the turning of the slide rod C, on its longitudi nal axis and insures the accurate alinement of the punches E,'G, and H, with relation to the receivers or holders d, (Z (Z carried by the forward disk D of the intermittent rotor D. 1 v 1 The shank e,'of the punch E, is rigidly mounted in the socket 0 of the cross head C 7 (Figs. 5 and 10). This punch E, per forms a double function in that it supports the mandrel 6*, used for theformationof the socket w ,.in the cylinder-00, of ."comw 7 pressed depolarizing agglomerate, and also transfers the latter from they matrix on, in the mold-block M, into the holder (5, in r the forwardingdisk D of the intermittent" 1 rotor 5D; "By 'reference to Figs; 1O-and'16',

it willbeseen that'in the retracted position ofthe punch E, the mandrel 6" extends into. the matrixm, of the mold block 1M, which ,is' rigidly attached'tothetab1e of the machine. The feed 10f 'ag'glol'nerate toQthe' matrix 5m, and fits icompr'ession j therein is timed to take place" during-'the retractileI a movement of the cross head C so that the -V matrix m, willfbe charged 'preparatory to the next forward oroperativefthrust of the T P ches.

The latter is rotated continuously, and is formed to provide for the rest of the leveri, for about two thirds of the rotation of said cam,'the other third, the thrust, beingemployed to raise the pusher 9, out of the way of the radial arms n, of the conical feeder N, when the latter is partially turned to effect a fresh feed of agglomerate to the discharge orifice 71?. The hub j, of the cam J, is formed with a gear jfiwhich derives its motion from the gear7c ,-aifixed to the main drlve shaft K,

to the table a. Tothefront end of the countershaft L, is secured the crank Z to which is pivotally attachedthe connection rod 'Zf, al-sdpivotally attached to the ratchet lever Z jc arryingthe pawll", which engages with the ratchet wheel Z1, ,which is rigidly attached I to the rear end of the shaft 1?; V which 1 is ournaled in the; bearing sleeve 0, (see Fig. 5)1 forini1'ig-pa'rtofthe' bracketofl which:supportsthe hopper N, said bracket 12,- being rigidly attached. to the standard 0f", securedito the front of-the'table a; To

Z ,'-t0 advance the ratchet Z one notch for each revolution of the power shaft P, thereby turning the conical feed member N, onetwelfth of a rotation on its axis, and bringinga freshcharge of agglomerate-m, into coincidence with the discharge orifice n, to be ejected therethrough intothechute n, by the pusher g, operated by the spring 9 when the former Q, has been raised by the cam J, acting through the medium of the roller 11, lever i, and roller 9 against the action of thespring g Thelowerend of the former Q, is formed with a semicylindrical concavity 9*, (Fig. 12) to correspond to the semicylindrical matrix m, in the mold-block M; and the descent of the former Q, compressesthe agglomerate charge of depolarizing materialm, laterally inthe matrix m, around the mandrel e as-illustrated in Fig. l0,said mandrel 6", being a reduced extension of the forwarding punch E, bywhich the hollow cylinder of agglomerate thus formed is transferred from said matrix m, into the cylindrical holder 03, which is in coincidence with said 'matriX m, as shown in Fig. 11. I

By a comparative reference to Figs. 10 and 11, it will be seen that the matrix m, (including the opposed concave surface of the former Q) is longer than the bore of the holder d, inthe carrier D and that the transfer plunger E, during the transfer thrust compresses the already laterally compressed-charge endwise against the abutment 0,, thereby still further compacting the ma:

terial and reducing the length of the charge It will also be to that of said holder cl. noted that the length of the mandrel 6?, is

greater than that of the matrix m, so that (near the termination of the forward thrust insuring accurate alinement of the mandrel,

and consequently of the socket 00 (Fig. 22) V forme'dtherebyz;

This feature of positive mandrel- 'e*',' so-as to" attain absolute axial alinement of the socket 00 in the body of agglomerate-w, is an important factor in the productionof a'perfec't product, i. e., a batcentralizing the te'ry element inwhich the carbon rod w,-is in V absoluite axial alinement as related to'th'e body of depolarizing material m,- thus rendering the element as a whole more effective and long lived, because any inequality of agglomerate around the carbon rod results in curtailment of efiiciency, since the thinner side is m in the charge w, bymeans of the mandrel 6*, during, the molding and compression of the charge instead of forming a solid charge and subsequently piercing the same as in our copending application for patent .hereinbefore referred to, We obviate all I danger of disturbing or loosening up the compressed material by the entrance of the perforating punch and the displacement of the material to form the puncture.

Thebearinga in the abutment a is of a diameter substantially the same as that of the mandrel. e itself, the difference being only suflicient to admit of the; snug entrance of the end of themandrel into said bearing a and the end of the mandrel e", is preferably chamfered or rounded oif to facilitate its entrance into said bearing a During the formation of the charge :12, and its transfer to the holder d, as above set forth the'punch E, and mandred c", are

rotated for the purpose of preventing the adhesion of the moist agglomerate thereto, and to render the socket 00 and body m,

smooth and true. The rotation ofthe mandrel 6*, also compensates for any possible bend or deflection of the mandrel laterally sinceobviously by such rotation the resultant socket is sure to be of perfect axial alinement. i

"The rotation of the plunger E, and lts mandrel extension 6", is effected by means of teeth on the'plungershank e, and on the the sprocket chain f engaging with sprocket hub i rigidly secured to the rotatable shaft '7, ,This shaft 7, is mounted in and between atbearing 0 integral with the upper arm of the cross head 0", and a bearing a, formingv part "of a standard a, rigidly attached to the top of the box-bracket a the V shaft f being formed with alongitudinal groove? 7 f, 'forengagement with a key pin 7; (see 7 Fig. 20) in thesleeve'f", which 'is mounted inithebearing a", of the bracket standard e2 Thefkeyaf and, longitudinal groovei 7 couple the-sleeverf and-shaft i so that" they rotate together while allowing the shaft f tofslide longitudinally insaid sleevef. On the'rear endof%said sleeve f, is rigidly attached. the sprocket, wheel -ff =which is connected byfthe sprocketmjchainif with sprocket teeth on the hub y, of'the' camJ;

l "Asthe mandrel e", and forwarding punch E, recede with the crosshead 1G,, and other punches mounted: thereon, the intermittentrotorgD, makes one-third of a turnfby reason of the one-third turn of the intermittent shaft R, acting through the gears r, is, and d, thus carrying the holder cl, with the compressed and axially recessed or apertured cylindrical charge 00, of depolarizing agglomerate over into coincidence axially with the placing punch Gr, (see Figs. 30 to 32 inclusive) by which the carbon pencil or rod m, Fig. 21) is inserted in the axial socket or aperture 00 formed for it in the bobbin or cylinder 0, by the mandrel 6*.

The carbon electrode rods 02 are fed to the axial pocket 9, in the sleeve g, in which the forwardingpunch G, operates, from a hopper S, which is rigidly supported upon. the bearing sleeve a, forming the top of the standard a, which is rigidlylattached to the :bracket a, which forms a forward exten 4 and 15) the rear end of said shaft 8 hav-- ing rigidly attached to it the ratchet wheel 8 which is actuated by a pawl s, pivotally supported between the twin rock levers s 8 (see Figs. 4 and 8) fulcrumed on said shaft 8 said rock levers s s beingoscillatcd by means of the pitman s,to which they are pivotally connected,-and said pitman 3", being reciprocated by reason of its plvotal connection with the crank-sprocket wheel 8 rigidly mounted on the'rear end of the shaft 8 (Fig. 8) which is journaled in the bearing sleevea on the end of the .ex-

tension arm a, of the bracket (2?, which is rigidlysecured to thetop of the box. bracke a as shown particularly in Fig. 15 j The crank-sprocketwheel s is connected by a sprocketfchain s", with the'sprocket. .wheel f, on the sleeve f5, of shaft which is slidably mountedfya's hereinbefore stated,

in. said sleeve f and the bearing of, on 7 said stan'clard'a Hence the shaft '8 rotatcsin uniso ith said lid f ywhih j shaft f, and its sleeve fF,' are rotated the i sprocket chain f which engages with the a sleeve sprocket f, and, withthe sprocket teeth inthe hub j, of the cam J. Sinceth cam J, makes one rotation for ea'ch'rotation j of. the intermediate sprocket' wheelsfand' chains, the shaft 68?, and crank sprocket sf,

will also rotate'once for each rotation of the Power il tandl hence the pitmanrsfl will. g

rock 'the pawl levers S once-during that period causing the awl 3 to advance; the ratchet Wheel '8 su ciently .to release a car bon rodm', from the hopper.

The latter are thus delivered successively to the inclined way 8 by which they are delivered, if perfect, to the axial pocket 9,

"of the-power. shaft-Res hereinbefore: de l scribed, it is. obviousthatthrough the means a a in-the sleeveg, mounted in the fixed hearing '8 Iffbrokenor imperfect they drop from the feed 'wheel s,fthroug'h'the'relief exit 8'', into a receptacle 8 provided for the purpose. The-relief exit s, is shown in cross detail in'Figjl l, in which a perfectrod is. shown in dotted lines as bridging the or defective ,rodsdiscarded as above stated.

That is to say there is always a surplusof rods on said feed way 8 the lowest rod in the column, restinginv the axial groove ,g,

' with the others in alinement above it.

When' the punch G, advancesit encounters the lowest rod, that in the axial groove 9, and causes thelatter to push the lastpreced ing rod into the aperture in the tubular c'ylindrical charge in the holder d, as shown in Fig. 81. At this point the head 0 of the cross head 0, encounters theforward extension g of the sleeve g,.on which is the collar 9 between which collar 9 and the washer g; is interposed :the coiled spring 9?; saidwasher 9*, bearing against the which sleeve 9, rests. j

The continued advance of the cross head C' presses back the sleeve 9", against the resistance of the spring" 9 pushing'the rod 00, farther into the aperture of the tubular cylindrical charge 0a,.as shown in Fig. 81, and bringing thetip 9. of-thechargepresser 9 into contact with the outer end of the charge ofagglomerate At the same time the tip a", of the abutment 21 is advanced into contact with the other end of charge w, the two tips gf and a exerting bracket bearing .g, and closing the bearingin an endwise pressure thereon and compressing it longitudinally. I

During 1 this endwise pressure on the charge m both nipples or tips a and g are partially rotated on their "axes for the purpose of smoothing the ends of the blankand preventing theinaterial thereof adhering to said nippleswhen they are withdrawn.

The stemof' the charge presser gfl is threaded to engage "with a female screw 7 thread formed for it in'the sleeve andits partial rotation is effected by means of a pitman s pivotally connected with an arm (Fig. 27 of the" rod presser gQand with the crank disk ,s? ,m (Fig; 12) on the front end of the shaft 8 Thus thepartial rotation of therod presser g, not only twists the face of the nippleg, in contact withthe the end of the charge m, but also, by reason of its screw connection with the sleeve g,

is releasedfrom the causes said nipple g", to compress the charge longitudinally as before stated withthe opent a, the upper end of said pitman a being connected with the strap of an eccentric a, 0n the'shaft 8 The rotation of the eccentric a, causes-the pitman a to rock the abutment a against the resistance of the spring a, (Fig. 25,) interposed between a nut collar 0;, on the end of the'spindle 04 and the bearing sleeve a", rigidly secured to the box bracket a and'within which said spindle shank a ,"is' mounted. This spring a, tends constantly to draw the abutment a back with its radial pin a,

in contact with the cam surface (1,, on the 'bearlng sleeve a, as shown more particularly in Figs. '25 and 26, and to hold said pin a, at the rear end of saidcam surface. Thus when the eccentric a, raises'the pitman a, the pin a, will'be forced up the cam surface a against the resistance of said spring 0., thereby not only rocking the nipple a to twist its surface in contact with the rear end-of the charge of agglonierate 00, but also advancing said nipple a", so that it compresses the agglomerate charge 00,1endwis'e against the resistance of the opposed nipple g on the charge presserghfo'f the sleeve 9, as shown inFig. 29 r The next one-third rotation of the carrier disk D brings the "holder d, into coincidence with the ejecting punch H The charge arrives in this position with'its rod 00, protruding forward as shown in Fig. 16. When the1punch H, comes in contact with the protuberant end'of the rod 00', it forces the latter into the tubular cylindrical charge 05', so that the rodm projects to the rear of the charge 'w,"an d' is flush with the front end thereof as shown'in Fig. '17. "It also contacts with the front end of the cylinder. of agglomeratafand for this reason is given a rotary 'motion to prevent its adherence thereto.

This rotary motionv is imparted to the shank h; of'the punch H, by means of a otherwise, as may be found most expedient.

The shank g, of the plunger' G, is mounted ina bearing sleeve 0 supported adjustably in a bushing 0 rigidly secured to'the socket 0 of the cross head C. 'Said shank g", is formed with a malethread engaginga female thread formed for it in minuted material around the mandrel to form a-tubular charge, andmeans for autosaid bearing sleeve 0. Said shank g..', is also provided with a handle 9 or equivalent by which it may be turned to regulate the extent of protuberance of the plunger A set screw 9 may be used to secure the shank g, in prescribed position.

The bearing sleeve 0, is also formed with a malescrew thread a, engaging with a a female thread formed for it in the bushing 10 0 so that the said sleeve 0, may be adpactness required, as well as also a desired predetermined length of the finally compressed charge.

It is obvious that various modifications may be made'in the construction shown in the drawings and above particularly de: scribed within the principle and scope of our invention. f j
